Narrative:
On final approach at approximately the outer marker a call for flaps 25 was made and the pilot monitoring attempted to select the requested flap setting; but the flap indicator showed that the flaps moved from the 20 position and stopped at 22 on the indicator and remained in that position. A trailing edge flap disagree light from the EICAS illuminated. A go-around was performed and the appropriate checklists were performed. The company and dispatcher as well as the cabin crew and passengers were informed of the situation and the flight crew decided to have the airport crash crew standing by as a precaution. A normal landing was made with flaps at the 22 position on the indicator and at about 7 KTS above the normal flaps 30 landing speed. A normal taxi in and shutdown at gate occurred without any ground assistance. An unknown failure or lockout of the flap system caused the flaps to stop at the position of 22 on the flap selector when flaps 25 was selected on final approach at about the outer marker.
